At their first meeting, a remarkable bond was sparked between the Dalai Lama, one of the world's revered spiritual leaders, and psychologist Paul Ekman, whose groundbreaking work has helped define the science of emotions. Here they share their thinking about science and spirituality, the bonds between East and West, and the nature of our emotional lives in a series of conversations. The Dalai Lama and Ekman push toward answers to the central questions of emotional experience: What are the sources of hate and compassion? What does science reveal about Buddhist meditation? And what can Buddhism gain from the scientific method?
